The Memphis Commercial Appeal reports that the City Council and County Commission may vote on a public financing plan for a new $250 million basketball arena on June 4.  That comes a week after David Stern is expected to visit Memphis.  Both elected bodies could vote on the financing plan as well as an arena lease agreement for the Grizzlies June 4.  At the same time, the University of Memphis is attempting to negotiate a change in financial arrangements for the Pyramid.  They fear construction of a new NBA arena could cost them $2 million per year.
